CFC are not recommended to be used in refrigerators because they
(b) affect environment
Explanation:
CFCs are chlorofluorocarbons which are harmful for the environment. They were commonly used in older refrigerators.
They are not recommended for use anymore because they are a major reason for ozone layer depletion.
The thin layer of ozone in the stratosphere protects the earth from the harmful UV rays of the sun.
CFCs breakdown this ozone into oxygen (O₂) and nascent oxygen [O] thereby increasing the penetration of UV rays which cause different skin diseases and cancer in humans.
